Abstract
PESILA-REDD will employ integrated methodology to address gaps in the evaluation of payments for environmental services (PES) and their cost-effectiveness in Reducing Emissions from Deforestation and forest Degradation (REDD) in developing countries. The proposal?s scientific innovation lies in bringing together novel quantitative impact evaluation (IE) methods, with qualitative policy assessment methods, to address six specific methodological challenges: (1) PES policy enabling conditions, (2) transferability of impact evaluations between governance contexts, (3) trade-offs between environmental services, (4) controlling for sampling bias in quasi-experiments, (5) spill-over and neighbourhood effects and (6) determination of policy benchmarks. Case studies will be conducted in Costa Rica and Colombia.
